WILLIAM S. SCHWARTZ, OF AMITY, OREGON.

LEMON-SQUEEZER.

To all whom it may concern:

Be it known that 1, WILLIAM S. SCHWARTZ, a citizen of the United States, residing at Amity, in the county of Yamhill and State of Oregon have invented a new and useful Lemon-Squeezer, of which the following is a specification.

This invention relates to presses, and has forone of its objects to provide a device of this character for expressing the juices from various fruits, and particularly lemons, and in this connection it should be stated that the invention is specially designed to serve as a lemon squeezer.

A furtherobject of this invention is to provide a portable press which is adapted to express the juice from a number of lemons in one operation, and catch and deliver the juice to a receptacle.

A still further object of this invention is to provide a press of simple construction, easy of operation and cheap to manufacture.

In the drawing :-F1gure 1 is a side elevation of the invention, showing the press clamped to a support. Fig. 2 is a vertical sectional view of Fig. 1. Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2, and Fig. 4. is a detail View of the clamping member taken on the line 4 4. of Fig. 1. Fig. 5 is a top plan view of the juice expressing means.

Referring to the drawing, 1 designates a circular bowl which is provided with an outlet opening or spout 2 at its lower side. In tegral with the bowl is a clamp comprising a yoke 3 having a threaded opening 4 in the horizontal lower portion thereof, said opening being adapted to receive the clamping screw 5, and downwardly extending diverging legs 66 which are outwardly inclined and spaced a art, thereby forming a fork which stradd es the vertical plane of the clamp. It will be observed that the undersides 77 of the legs 66 are upwardly inclined from the inner edge outwardly, a feature which causes the bowl to assume an inclined position with relation to the table or other support 8 when the device is clamped thereto by the thumb-screw 5. The hori zontal lower portion of the yoke is parallel with the lower face or underside of the legs, so that the screw may engage the underside of the table properly when the parts are applied. Extending above the bowl 1 and integral therewith is a cone 9 which is arranged within the center of said bowl.

Specification of Letters Patent.

Application filed February 15, 1908.

Serial No. 416,139.

The cone is provided with a vertical wall at its base, which wall is formed with a series of threads 10. V

A cylinder 11, which is formed with a series of internal threads 12 at its base, is screwed onto the cone 9 engaging the threads 10. Said cylinder is provided with a seriesof spaced vertical slots 13 that terminate short of both the top and. bottom of the cylinder, the lower ends of the slots being outwardly inclined as shown at 14. The cylinder is further provided with a plurality of outwardly extending vertical ribs 15, preferably arranged diametrically opposite one another, and which are provided with a vertical series of threads 16, extending throughout the length of. the ribs. These ribs'are cast on the outside of the cylinder; their upper ends are arranged flush with the top of the cylinder, and their lower ends terminate short of the bottom ends 14 of the slots 13, and thereby form an opening or outlet 17. As shown, four of the vertical externally threaded ribs are provided, but the precise number is not material. They are arranged to project beyond the circumference of the cylinder, as will be seen by reference to Fig. 3.

The invention further embodies a juiceexpressing element com rising a ring 18, that is provided interiorly with a series of threads 19 which cooperate with andengage the threads 16 of the spaced ribs 15. Extending upwardly, and integral with the ring 18, is a U-shaped hail 19*, the horizontal portion 19 thereof being arranged directly over the center of the ring. This horizontal portion or arm 19 is preferably of greater thlckness than the two vertical arms or portions 1919, and it is provided with an opening or bearing 20, which is located in the center of said member and directly above the cone 9. Depending from the horizontal arm and extending near to or below the bottom of the ring 18, is a plunger comprising a concaved body portion, forming a hollow conical shaped head 22, which is located in the lower end thereof and is of substantially the same vided at its extreme end with a series of L threads 24, engaged by a nut 25, which secures the plunger to the bail of the expressing element, but allows it to revolve as on a swivel. Integral with and outwardly extending from the ring 18 are two handles 2727, arranged diametrically opposite each other and in alinement with the bail.

It will be observed that the clamp is secured to a support, the bowl is arranged above the clamp and in alinement therewith, and also that the juice-expressing device is carried by and arranged above and in alinement with both the clamp and the bowl. Thus it will be seen that, when in operation, the pressure exerted is a direct pressure upon all the elements, as they are all in alinement with each other, and consequently there will be no lateral strain upon any part of the de v1ce.

The operation of the press is as follows The bowl is clamped to any support, prefer-v ably a table, by the thumb-screw 5, and the cylinder 11 is screwed onto the con-e 9. A number of lemons are cut into halves, and

' these are placed, one upon another with their fiat parts downwards, within the cylinder, the lower one resting upon the cone. The expressing element is then screwed to the outside of the cylinder, the hollow conicalshaped head of the plunger bearing upon the lemons. By continuous rotation through the handles 27-27 the ring will be forced downwardly, carrying with it the plunger, which does not revolve owing to its swivel connection with the bail 19. This movement is continued until suilicient pressure has been exerted upon the lemons to express all of the juice. It will be observed that when the juice is forced from the lemons, it passes out from the cylinder through the slots 13 into the bowl 1.' The juice, which finds its way into the slots directly behind the ribs 15, will travel down said slots and pass out through the openings 17 into the bowl. As the bowl is slightly inclined with respect to the support, the juice will flow from said bowl through the outlet 2 into any suitable receptacle that is positioned onthe table below the said spout.

The detachable connection between the cylinder and the cone, and between the cylinder and the expressing element, permits of the thorough cleaning of the parts, so as to free the apparatus of any accumulation of pulp or other parts of lemons. Moreover the screw pressure provided by this invention allows for a more thorough and quicker extraction of the juices of the fruit.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
